What is a NASA Science Update?

Major Hubble discoveries on NASA television ... Astronomers explain their Hubble discoveries at a press conference, called a NASA Science Update (NSU), broadcast on NASA television. The NSU includes a question and answer session with members of the media.

May 31, 2012: NASA astronomers announced Thursday they can now predict with certainty the
next major cosmic event to affect our galaxy, Sun, and solar system: the titanic
collision of our Milky Way galaxy with the neighboring Andromeda galaxy.

The Milky Way is destined to get a major makeover during the encounter, which
is predicted to happen four billion years from now. It is likely the Sun will be
flung into a new region of our galaxy, but our Earth and solar system are in no
danger of being destroyed.
